be quiet! TFX Power 3 Bronze is the second smallest TFX power supply format from the German brand be quiet!. Compared to Flex-ATX, it has a larger and therefore quieter fan with a diameter of 8 cm. As well as a large number of cables, including for a 6 + 2-pin video card. Simply put, you can connect a video card up to 150 watts.

The TFX Power 3 has only one rated power - 300 W (peak all 350 W), but you can choose an energy efficiency certificate: Bronze or Gold. The second one has a higher efficiency (90 vs. 85%) and an even quieter fan. Despite its compact size, the power supply weighs almost a kilogram, which is the reason for the solid CWT circuitry and large aluminium heatsinks.

Up to half the load on the PSU, the fan emits an almost indistinguishable 15 dB, and at maximum load it spins up to 1800 rpm, which results in already tangible 29 dB. This is achieved by a four-pole motor for better alignment and a long life screw threaded ball bearing.
